Abstract
The conversion of CO2 to valuable substances (methane, methanol, formic acid, etc.) by photocatalytic reduction has important significance for both the sustainable energy supply and clean environment technologies. This review systematically summarized recent progress in this field and pointed out the current challenges of photocatalytic CO2 reduction while using metal-organic frameworks (MOFs)-based materials. Firstly, we described the unique advantages of MOFs based materials for photocatalytic reduction of CO2 and its capacity to solve the existing problems. Subsequently, the latest research progress in photocatalytic CO2 reduction has been documented in detail. The catalytic reaction process, conversion efficiency, as well as the product selectivity of photocatalytic CO2 reduction while using MOFs based materials are thoroughly discussed. Specifically, in this review paper, we provide the catalytic mechanism of CO2 reduction with the aid of electronic structure investigations. Finally, the future development trend and prospect of photocatalytic CO2 reduction are anticipated.
Highlights
Energy shortages and environment issues are global problems and challenges that are faced by human beings today [1,2,3,4,5,6]
Metal-organic frameworks (MOFs), which are known as coordination porous polymer, is a class of crystalline porous materials constructed by the coordination bond between metal ions or metal cluster nodes [17,18,19,20,21]
The results showed that the single UiO-66-NH2 showed no activity for photocatalytic CO2 reduction, but Cdx Zn1-x S with adjustable composition and band gap could be efficiently excited by visible light
Summary
Energy shortages and environment issues are global problems and challenges that are faced by human beings today [1,2,3,4,5,6]. Metal-organic frameworks (MOFs), which are known as coordination porous polymer, is a class of crystalline porous materials constructed by the coordination bond between metal ions or metal cluster nodes [17,18,19,20,21] These materials have been widely used in gas separation/storage, catalysis, sensing, proton conductors, and drug delivery because of their structural diversity, design/modification, and ultra-high specific surface areas [22,23,24,25]. The high specific surface area of MOFs is helpful for the gas reactants adsorption around the active site This is beneficial to the molecule activation and catalytic transformation in the subsequent process [45,46]. The current challenges and future development trend of MOFs-based materials for photocatalytic CO2 reduction are anticipated
